To all lwhom it may concern:

Be it known that I, CARL WEBER, a citizen of the United States, residingat Chicago,

in the county of Cook and State of Illinois,

' have invented acertain new and useful Imrovement in Holding-Gli s forConcreteeinforcement, of which t e following is a specification.

My invention relates to a holding clip for concrete reinforcement andhas for its object especially to provide means for supporting thereinforcing structure of concrete walls before the concrete is ap liedthereto. and before it has set. It has or a further object tofurnish acombined supporting and spacing means for concrete reinforcement wherethe concrete is to be distributed by a cement or the like over thereinforcing structure fastened to and spaced from a plane andparticularly a perpendicular surface. It has for another object tofurnish a simple holding clip which can be quickly and easily secured tothe supporting surface or member by a single nail or screw or the Myinvention is illustrated more or less diagrammatically in theaccompanying drawing, wherein- Figure 1 isa front view of the clip inplace sup orting a metal netting; v

Fig. 2 1s a vertical section of the clip supportinga metal netting andsecured to the holding surface; and f Fi 3 is a perspective View of theclip secue in place and holding a reinforcing ro Like parts areindicated by like characters in all the figures.

A is the iiat front surface or ybody of the clip perforated in its upperend at B to receive the nail C which holds the clip in place. Extendingat right angles from the body or front of the clip are the limbs orflanges D, D, the outer edges of which may be at various angles to thefront'of the clip, but are preferably parallel thereto.' These limbs arenotched in their u per edges at E, E adjacent the frontI of the clip insuch fashion as to be joined tothe front of the clip only vby the narrownecks F F, the

v .breadth of which may be varied as .required front or top of theclip'into the backing orA supporting surface G. Obviously a screw, bo tor rod or similar fastening could be used if found necessary andeflicient. The notches E, E in the Iup er ed es serve as hooks tosupport the nettlngs, I, the rods J or other reinforcing members whichmay be used. The nail serves to hold the'reinforcing members in place inthe'supporting notches. These drawingsare in a sense diagrammatic and itwill be understood that variations 1n the form and disposition meng7 oft e part's may be made without departin` from the spirit of myinvention.

he use and operation of my invention are as follows My invention isespecially tted for use with that formof concrete wall structure .whichconsists of the application -of reinforcing members to atemporarybacking of wood and the like and the subsequent distribution 'over thereinforcement and'` against the backing metal lathin and the like for reproofing walls and cellings, and in the laying of ceme'nt or concretefloors, and in other methods of reinforcing and lathing not heredescribed, for use with liquid orv plastic materials. In its use thereinforcing members are supported orhooked into the notches in the cliplimbs. The nail or other fastening are hard to drive in and easily bent.Thev nail also closes the top of the notches locking the reinforcementin place in the clip.'

Since the supxportin nail is well above the bottom of t takes itseilicient vertical position when applied to a vertical surface. Whenused on a orizontal surface the nail, since it closes the slot, preventshorizontal motion on the part ofthe reinforcing members. YObviously the11o or supporting surface of Huid concrete driven from a cement gun. 4It can also be usedl in the ap lication of e note es the clip naturallyedges of the arms which engage the joist beamer backing could beinclined to they be applied by any means and so, of course, K

it is understood that the specification is,not to be limited to anyparticular situation, arrangement or kind of concrete.

l claim 1. As a new article of manufacture a U-shaped holding clip forconcreteJ remforcing members havingl atop provided at its forward edgewith a hole to receive the securing nail and two sidelimbs ,providedwith bottom edgesl to give a long bearing against the wall and providedeach with a deep notch entering from its front edge for the reception ofthe reinforcing member the parts so proportioned that the nail when 1nposition closes the notches so as to hold the reinforcing member inplace.,

2. As a new article of manufacture a U-shaped holding clip for concretereinforcing members having a top provided at its forward edge with aVhole to receive the securing nail and two side limbs provided each witha deep notch entering from its forward edge the parts so proportionedthat the .nail when in position closes the notches is out of contactwith the member and lies between the two limbs. i

against the wall and provided each with a deep notch entering from itsfront edge for the reception of the reinforcing member the parts soproportioned that the nail when in position closes the notches so as tohold the reinforcing member" in place, the U- V shaped clip being openon three sides and closed only on the top so as to permit free entrance`of the mortar to lill the inside of the clip and surround and embed thenail.

Intestimony whereof I aiiX my signature in the presence of two witnessesthis first day of April, 1918. i

CARL WEBER.
